IMPROVED MACHINE FOR MAKING METALLIC TUBES 0R SPOUTS.

Specification forming part of Letters Patent N0. 19,045, dated July 25, 1865.

To all whom it may concern.-

Be it known that we, ELIJAH VALENTINE and MOSES T. RIDOUT, both of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Machine for Forming Metallic Tubes or Spouts; and we do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a top view of our machine; Fig. 2, aside elevation thereof when at rest; Fig. 3, a front elevation with the forming-roller raised so as to allow the introduction of the metallic blank; Fig. 4, a transverse section in the line 00 :20 of Fig. 1, with the forming-roller or mandrel F forced down between the auxiliary rollers EE by the pressure-arms M N. Figs-5 and 6 are respectively detached front and rear elevations of the block supporting the smaller ends of the auxiliary rollers; and Fig. Z is a "ertical section of said block in the line 3 y of Fig. 5, showing the arrangement of the spring-actuated rod G, supporting the journal of the forming-roller at this end thereof.

' Similar letters of reference indicate like parts in each of the figures. V

The nature of our invention consists, primarily, in a peculiar combination and arrangement of a series of tapering rollers for the purpose of rolling up metallic blanks into tubes or spouts; secondly, in the combination of an upper forming-roller or mandrel capable of being readily detached and elevated from its bearings at either end with a series of auxil iary stationary rollers which shall-partially surround the same when in operation.

The bench or table A, supported upon the standards B B, Figs. 2, 3, and 4, forms the bed-plate of our machine. This bed-plate A may be made (as illustrated in the drawings) of a width somewhat greater than the length of the tubes or spouts to be formed in the machine. To its side edges are secured suitable metallic blocks or frames, 0 and D, Figs. 1 and 3, in which are placed respectively the journal-boxes for the front and rear ends of the stationary auxiliary rollers E E E and of the forming-roller or mandrel F. These rollers are all equal in size and uniformly tapering.

The arrangement of the journal-boxes for the stationary rollers E E E is'similar in both frames G and D, and is illustrated inth'e detached rear view of the block D in Fig. 6 of thedrawings. These journal-boxes a ao are let into dovetailed recesses formed on the innor face of each block. The journal-box a for the lower roller, E, is placed in the center of the block,and theremainingtwo,aanda,above it, on either side thereof, as seen in Fig. 6. The journal-boxes (t a for the side rollers, E E, placed in the horizontal recesses, are secured, and at pleasure adjusted, by means of setscrews b b working in suitable side pieces, 0 c, secured on the ends of the block, as seen in Figs. 3, 5, and 6.

The two side rollers, E E, are prolonged outwardly at their larger ends through apertures in the block 0, and are fitted with small cog-wheels S S of equal diameters, as seen in Figs. 1 and 2. A central notch or recess is cut down vertically in each of the blocks G and D to the level of the bearings of the side rollers, E and E. The lower portion of the notch in the block 0 forms a bearing for the larger end of the central forming-roller or mandrel, F, whose opposite smaller end is received into a Y upon the upper end of a rod, G, whose lower end drops into an inclosing-recess in the block D, and rests upon a spiral spring,f, contained therein, all as clearly illustrated in Figs. 1, 5, 6, and 7. This forming-roller or mandrelF extends outwardly at its enlarged end, and, passing through a slot in a guiding-piece, K, secured to the outer face of the block O,as shown in Figs. 2 and 3, terminates in a crank, H, Fig. 1.

A cog-wheel, W, equal and similar in all respects to the cog-wheels S S upon the ends of the auxiliary rollers E E, is fitted upon this projecting end of the forming-roller or mandrel F, so as-to gear into the same, the intervals between the cog-wheels S S being such that when the mandrel F drops down between the rollers E E and rests upon its bearing in the frame 0 its wheel WV will engage with each of said wheels S S on either side.

In order to press down the bearing in which the journal at the small end of the formingroller or mandrel F rests, and which is otherwise kept elevated by the spring f, and to keep sai'd roller down between the auxiliary rollers E E E", as seen in Fig. 4, while the spout is being formed thereon, two curved arms, M and N, are pivoted to the bed-plate A, so as to reach over and bear upon said forming-roller. The free extremities of these arms M and N are so recessed (see Fig. 2) as to fit accurately upon the roller, and the one, M, fits down thereupon immediately over its bearing in the block (J, and the other, N, immediately in the rear of its bearing in the Y of the spring-actuated rod G, as seen in Figs. 1 and 3. These curved pressure-arms M and N are connected together by'a stout cross-bar, O, and to the center of this cross-bar is hinged a long link, P, which passes through a slot in the bed-plate A, and is hinged at its lower end to the center of the lever Q, whose rear end is pivoted to the under side of the bed-plate, andwhose front end extends out in front of the machine, and there terminates in a handle, all as clearly illustrated in Figs. 2 and 4 ot' the drawings.

A stout spring, It, is so secured under the lever Q, as seen in Fig. 4, as that it will keep it, when at rest, thrown up, so that the connected pressure arms M and N shall be held up clear and free from the forming-roller F, as seen in Fig. 2.

In forminga spout or tube with our improved machine, a suitable metallic blank of the proper size and shape is laid upon the two rollers E and E under the forming-roller or mandrel F, whose smaller end, resting in the Y of the rod G, is elevated by the power of the sprin g f, and whose larger end the operator will himself raise by means of the crank H. By exerting pressure upon the lever Q the arms M and N are then brought to bear upon the mandrel or forming-roller F, at either end thereof, with sufficient power to force it down, bending and carrying the blank with it in between the auxiliary stationary rollers E E and upon the lower roller,E. When the mandrel F is thus borne down between the rollers E E its cog -whee1 W will engage with their cog-wheels S and S, so that its revolution will cause these auxiliary rollers to rotate with equal velocity, and the spout formed thereon to be readily removedtherefrom. In this way a thousand tubes for candle-molds or for can spouts, 850., may be easily formed in one hour, and as each roller moves in unison with its fellow the metal will not be broken, scratched, or in the least marred in the operation.

We contemplate operating the lever Q by means of a treadle, if found desirable.

Having thus fully described our improved machine for forming metallic tubes or spouts, what we claim therein as our invention, and desire to secure by Letters Patent, is-

1. The use and arrangement of two or more stationary rollers, E E, in combination with a detachable formin g-roller, F, partially inclosed thereby, when all of said rollers have a taper ing form and are made to revolve in unison with each other, substantially in the manner and for the purpose herein set forth.

2. In combination with a detachable forming-roller or mandrel, F, and stationary auxiliary rollers E E, the pressure-arms M and N, arranged and operating substantially as and for the purpose herein set forth.

3. The spring-actuated rod Gr, so combined with the supporting-block D and the pressurearm M as to form an adjustable journal box for the free end of the detachable mandrel F, substantially in the manner herein set forth.

The foregoing specification of our improved machine for making tapering metallic tubes or spouts signed by us this 12th day of November, A. D. 1864.
